如何在codeigniter中使用重定向显示验证错误？ [英] How to show validation errors using redirect in codeigniter?

问题描述

我已经处理了一段时间的问题。如何在函数中使用重定向设置验证错误？这是我在控制器中的代码：

I have been dealing with a problem for a while. How can I set the validation errors using redirect in a function? This is the code I have in my controller :

function send()
{
    $this->form_validation->set_rules('e-mail', 'Email', 'trim|required|valid_email');
    $this->form_validation->set_rules('cellphone', 'Cellphone Number', 'trim|required|is_natural');
    $this->form_validation->set_message('required', '%s is required.');
    $this->form_validation->set_message('valid_email', '%s is not a valid Email Address');
    $this->form_validation->set_message('is_natural', '%s can only contain numbers.');
    $this->form_validation->set_error_delimiters('<li>', '</li>');

    if($this->form_validation->run() == FALSE)
    {
        redirect ('/');
    }
    else
    {
        echo '<pre>';
        print_r($_POST);
        echo '<pre>';
    }
}

这是我在我的视图文件中使用的代码：

And this is the code I use in my view file:

<? if (validation_errors())
{   
echo '<div id="validation_errors" title="Error:">';
echo '<div class="response-msgs errors ui-corner-all"><span>Errors:</span><br /><ul>';
echo validation_errors();
echo '</ul></div>';
echo '</div>';
}
?>

推荐答案

我找到了办法。重定向不会使数据保持显示。我使用下面的代码来解决问题：

I found the way to do it. Redirecting does not keep the data to be shown. I used the code below to solve the problem:

if($this->form_validation->run() == FALSE)
{
    $this->index();
}
